The Hidden Oracle (The Trials of Apollo #1) by Rick Riordan

How do you punish an immortal?

By making him human.

After angering his father Zeus, the god Apollo is cast down from Olympus. Weak and disorientated, he lands in New York City as a regular teenage boy. Now, without his godly powers, the four-thousand-year-old deity must learn to survive in the modern world until he can somehow find a way to regain Zeus’s favour.

But Apollo has many enemies – gods, monsters and mortals who would love to see the former Olympian permanently destroyed. Apollo needs help, and he can think of only one place to go . . . an enclave of modern demigods known as Camp Half-Blood.

In this New series about the gods and demigods, the god Apollo has fallen from grace…yet again! He must complete trials set out for him by the Oracles, for which he is the deity of, but they are no longer working and have shut down…or have they?

He must complete these trials before his father will allow him back onto Mount Olympus and give him back his godly powers.

With some characters that we know from the previous Percy Jackson books, plus new characters and new dangers. Rick Riordan sets the stage and pace and weaves his magic, for another enjoyable read.
